APPLE BAKING, GORING, AND SLICIN' G MACHINE.

To all whom it may concern:

Be it known that I, WILLIAM EHRLIOH, a citizen of the United States, residing at Chicago, in the-county of Cook and State of Illinois, have invented certain new and useful Improvements in'Apple Paring, Goring, and Slicing Machines, of which the following is a specification.

My invention "relates to mechanism for paring, coring and slicing apples and other similar fruits and has for one of its objects the provision of a simple and efficient device of the character mentioned.

A further object is the provision of a device of the character'mentioned adapted to automatically pare, core and slice apples and other similar fruits.

Other objects will appear hereinafter.

An embodiment of my invention is indicated in the accompanying drawings, forming a part of this specification and in which- Figure 1 is a side elevation of a device embodying my invention; I Fig. 2 is a section taken on line.22 of Fig. 3 is an enlarged fragmental section taken on line 33 of Fig. 2;

Fig. 4 is an enlarged fragmental section taken as on line 4-4 of Fig. 2;

Fig. 5 is a fragmental view looking as from line 5-5 in Fig. 1;

Fig. 6 is a section taken on line 6-6 of Fig. 1; and

Fig. 7 is a view similar to Fig. 6 but showing parts in different positions.

Referring more particularly to the draws ings, I have indicateda frame 10 of suitable form to accommodate the parts hereinafter mentioned. This frame is preferably a casting and may be made up of one or more integral parts or castings when sodesired.

Journaled in the casting 10 in suitable bearings is adrive shaft 11 carrying a pulley 12 by means of which the shaft 11 is operated. On the shaft 11 is a pinion 13 meshing with a gear 14, the latter being journaled on a stud shaft 15 threaded in the frame 10, as at '16, or, secured tothe frame in any desirable manner.

A shaft 17 is also suitably mounted in the frame 10 and carries an intermittent gear 18 which cooperates with a suitable intermittent gear member 19 formed integrally with or secured to gear 14. Any suitable form of intermittent gear may be used. In

Specification of Letters Patent.

the form shown the gear 14 is adapted to turn three revolutions to one revolution of shaft 17.

On one end of shaft 17 I secure a head 20 which carries a plurality of apple-holding forks 21. In the present instance I have indicated three forks 21, but it will be understood that a fewer or greater number may be provided. as desired. The number of revolutions of gear 14 with relation to shaft 17 will correspond to the number of forks,

of gears 23 into mesh with gear 24 to operate one of the forks 21 at a time.

A collar 28 is provided on each of the sleeves 22 for holding said sleeves 22 against longitudinal movement.

Slidably mounted in each of sleeves 22 is r a pin 29 adapted for removing a core from a fork 21. Each pin 29 is moved in its sleeve to its position indicated'at 29 in Fig. 1 by placing an apple on fork 21. When the apple hasmovedaround until it has passed I a place where the apple, is completely pared and cored its corresponding pin 29 engages a cam 30 on the frame and moves the pin to its position indicated in the fork 21 near the lower side of Fig. 1. This movement of said pin pushes the core out of fork 21, discharging it from the machine.

Also, adjacent each ofthe forks 21 is a pusher 31 mounted on a pusher rod 32 which is slidably mounted in head 20. After the apple has been pared and cored a pusher 31 pushes the apple from its fork 21 over onto the coringknife 33, which will be described more in detail later. Each pusher 31 is moved .to a position indicated at 31' in Fig. 1 bypressing an apple onto its fork 21 and after the apple has been pared and cored the pusher is moved to the position indicated at the lower side of Fig. 1 by an arm 34 pivoted as at 35 on a bracket 36 secured to frame 10. The arm 34 is operated by a cam37 on gear 14 and timed so as to push the pusher to proper position after the paring and coring has been completed and before the fork 21 carrying the apple has been moved out of registration with the scoring knife 33; A spring. 38 serves 'to'hold the arm 34 in the'position'shown in Fig. 1, except when being'operated upon by cam 37 A friction roller 39' may be mounted on the arm 34 when so; desired.

provided a guide 40, which in'the present instance is indicatedas two rods. Slidably mounted; on this guide .40 isa carrier 41.

This 'carrier 41. has a vertical opening in, ,which is journaled a shaft 42, see Fig. 4;

0n the lowerjend' of shaft 42 is a bifurcated member 43 which has'two teeth "44,'as clearly 'indicated'in Fig. 31' These teeth 44 coiipe'rate'withrecesses 45in a guide member 46 secured under a suitable portion of the frame, as at 47.1At the top of shaft 42 is amember 48 having a slot 49 at one side thereof in which is pivoted a knife carrier 50, being pivotedasat 51. Themember 50 has part '52 extending away from sh aft I 42 to whichatension spring 53 is connected.

The g'gear 55 meshes with teeth I on! the 'carrier. 41;. Said gear 551 isjoperatedby a roller '58- mounted with m 59 whichislfi'xedon a shaft 60'. The l'oller 58f'operates in "aslot r clear howthe member 43 will turn through 58; in the" gear 55. y The. shaft'60 is rotated by a worm wheel 61 meshing with a worm '62 ona shaft 63, theilatterrbeing journaled in av suitable'part of the frame 10. The shaft 63-;is operated-by a pinion '64 fixed" thereon which meshes with gear 27. t On the'lower end ofmember 50 is a knife holder 65 having a suitable knife66 mount ed thereon in a manner to engage an apple 7 on the'forks 21,. one at-ja time; Themem ber 65 is preferably mounted so that it can along. 1As member 43 moves along member 180.,degreesin'goingin each-of-its direc- H tionsjof'reciproeating movement.

While I have indicated four knives 81 it will be apparent that as many or as few of these knives may be provided, as desired. It will also be obvious that the parings and cores are dropped near the same point and the good part of the apple is dropped at a different point so that the good apples can be kept away from the parings and corings, if desired.
